Engine casing, clutch. Oil leaking from bolt hole?

[Paulnorth]

I've changed oil and filter. Trying to locate oil leak. Coming from a machined hole, not sure if threaded. Only developed leak a few days ago. If anyone has any ideas why oil is leaking or something missing.
Its below the coolant drain bolt on clutch side.

That's a drain hole for oil and water.

Your water pump has seals either side of it, when the seals wear out this is to stop water getting into the engine or oil getting into the water system.

If oil is coming out it looks like maybe a seal is wearing out. 

Water and oil churning up together makes an awful yogurt type mixture and can cause major issues.

Thanks kwackboy,
No quick fix, other than new gasket?
I will take pump off and have a look. Pump bearings etc....cheers

[kwackboy]

You would need a clutch cover gaskit, a water pump cover o-ring and water pump seals, I think.

A drain as kwackboy said. Some engines it has extension as in pic then a black hose on it.
If oil leaks chance its the two water pump bearings worn and/or their oil seal letting oil into the drain.
If water then the sprung water seal is leaking cooling water past its ceramic face or rubber bit has a hole in it. Leaks due to age or wear are extremely rare.
No idea if you found this after or before oil change. The crankcase breather is close to the inside of the bearings and their oil seal. Over filling of oil can results in a fast oily mist fluctuating at pressure rushing past that oil seal. Might simply have overwhelmed the seal and will stop leaking oil with corrected oil level.
Only have clutch cover to take pics of. Hope explains it. Case of one bit needs changing then all parts need replacing. Not cheap bits but water seal is sold by the aftermarket people.
Oil seal the both bearings go into bore shown in second pic.
Water pump seal into bore in last pic.
You might find a tidy second hand cover with good pump from a low miles wreck cheaper and easier than new parts.

Thanks for the info.
I noticed the oil leaking prior to oil change. I thought it watch the sight glass. But on closer inspection oil leaking from breather hole. No tail end for hose. You suggest strip down and replace bearings and seals. I've not had the casing off yet..I agree, costly I'm sure.

[Paulnorth]

What servicing itemswill I need.
Or maybe best to strip down and order after inspection of defective parts?
Cheers

Kwackboy should be billing this site for his time and expertise. He's an asset, a Jolly Good Egg and a thoroughly nice chap to boot. ( I hate people like him.)

[kwackboy]

I'll share the credit with sharealike.

However I'll take loo roll as payment .. 

@ paulnorth.
Fix the issue first ..👍

 

[Paulnorth]

Aye your credit to the forum and great help. I'm working so will get bike sorted when I'm off....
Thank you

As a side note.

If the bike is a K2 it shouldn't have a black engine side case.
My guess is that that pump housing has been in bits in the past to be painted... likely for corrosion that these bikes all suffer around the water pump.
Could be corrosion caused due to the lack of spout and rubber pipe if they were removed for spraying.
We had a few with the same issue come into the dealers I was at. Mostly on older/high mileage bikes that had seen a bit of salt.

[Paulnorth]

Hi, not even sure what a K2 is, model wise.
First bike I've bought at age of 51. 2002 vstrom DL1000, 40,000 miles. I don't think it's been looked after. It only started leaking oil last week. I've done over 800 mile before. No prob. But was bad weather riding.
So is it the case of getting into casing and identifying what needs replaced. Or can I buy a serving pack?ty

[Paulnorth]

I do appreciate all the help blokes.ty

2002=K2, 2003=K3 etc.
2012=L2, 2013=L3 etc.

[kwackboy]

I'll with sharealike on the second hand casing option.
It's probably cheaper and the pump would probably be OK.

K2 is the first production year. Non adjustable screen, different instruments etc compared to the later classic Stroms. That's a lot of bike for a new rider!

[Paulnorth]

It is a big bike and engine. I'm just steady away. Not wanting to race around the roads. I'm in Northumberland. Enjoying and gaining experience one ride at a time.
